Okay, I need to create a professional and useful wiki-style document about "Deadlift" under the categories of Health -> Exercise -> Exercise Methods. Let me start by understanding the requirements.

First, the structure: H1 for the title, an overview section, several sections with H2 and H3 headings, and maybe references or related documents. The content needs to be accurate, objective, detailed enough, easy to read, and use technical terms with explanations. Also, markdown formatting with proper hierarchy, lists, tables, code blocks if needed, and at least 800 characters.

Starting with the title: "데드리프트" as H1. Then an overview section explaining what deadlift is, its importance in strength training, maybe some history or basic description.

Next sections. Maybe break it down into different parts like Technique, Benefits, Common Mistakes, Equipment, Variations, etc. Each of these can be H2 headings. Under each, more detailed H3 sections if needed.

For the technique section, I should explain the proper form step by step. Mention the setup, lifting the bar, maintaining posture, and lowering it. Maybe include a table for steps or common mistakes vs correct form.

Benefits: Physical benefits like muscle building, strength gains, functional fitness. Also mental aspects like discipline. Need to back these up with some general info.

Common Mistakes: Like rounding the back, using too much weight, improper grip. Explain why they're bad and how to avoid them.

Equipment: Mention barbells, plates, weightlifting shoes, belts. Maybe a table comparing different equipment types or their purposes.

Variations: Different deadlift styles like conventional vs sumo, Romanian, trap bar, etc. Each can be an H3 under Variations.

References: Maybe include some reputable sources like fitness organizations or scientific studies, but since I don't have real links, just mention them in a references section.

Need to ensure technical terms are explained. For example, "hip hinge" might need a brief explanation. Also check for accuracy—make sure the steps of deadlift are correct, maybe refer to standard guidelines.

Check the length: 800 characters is about 150-200 words. The entire document should be longer than that. So each section needs enough detail.

Avoid markdown in the thinking process but structure it properly in the final answer. Use H1, H2, H3 as needed. Maybe use bullet points for lists of benefits or mistakes.

Wait, the user said "최소 800자 이상" which is about 800 characters, not words. So around 800 characters. But the example response they provided earlier was longer. Maybe I need to make sure it's more than that. Let me check: the sample answer has several sections with H2 and H3, lists, tables, etc., which would add up.

Also, ensure that the language is in Korean, professional but accessible. Avoid overly technical jargon without explanation. For example, when mentioning "hip hinge," explain it as a movement where you push your hips back while keeping your back straight.

Check for any possible errors: like incorrect steps in deadlift technique. Make sure to mention key points like engaging the core, keeping the bar close to the body, lifting with legs and glutes, not the back.

Include safety tips, maybe under common mistakes or a separate section. Also, variations can be useful for different fitness levels or goals.

I think that's a solid plan. Now structure it step by step in markdown.
